Dynamic Model Of Used Cooking Oil Waste Management In Denpasar City

Abstract

Waste cooking oil (WCO) is oil that has been used for frying more than three times, so it is classified as  dangerous, which can endanger human health and also have a negative impact on the environment. The  city of Denpasar every month produces approximately 604,629 liters/month of waste cooking oil. Until  now, it has not been clearly managed. WCO, if appropriately managed, will be potential because it can  be processed into products and provide added economic value. This research aims to analyze the  potential of WCO management in Denpasar City and develop a design model for WCO management in  Denpasar City. This research was conducted using a dynamic system approach, and system simulations  were carried out from 2020 to 2030. The development of a dynamic model of WCO utilizes secondary  and primary data. The simulation results show the factors that influence the model's behavior, namely  the supply of household WCO, the supply of non-household WCO, and waste treatment technology. The  simulation results on existing conditions in 2030 show that the stock of waste cooking oil cannot meet  the demand for waste cooking oil. Based on the simulation results of several scenarios, alternative policy  recommendations that follow the objectives are scenario 4 (combined scenarios), which can produce a  supply of used cooking oil of 229,897.75 liters in 2025 and increase to 253,348.94 liters in 2030.
